Answer:
The strength of the electric field is
.
Explanation:
Given that,
Speed 
Time 
Angle = 45°
We need to calculate the acceleration
Using equation of motion




We need to calculate the strength of the electric field
Using relation of newton's second law and electric force



Put the value into the formula


Hence, The strength of the electric field is
.
Hey
The formula of kinetic energy is 1/2mv^2
So it depends on mass and velocity
As mass increases , kinetic energy increase .
So option b , the first rider had more mass is correct z
